This is quite a remarkable about-face for SD.
South Dakota is the only state in the union that prohibits internal possession of marijuana.
If you smoke pot in Colorado, then drive through South Dakota, you're in violation of their possession laws and are subject to a potential penalty of a year in jail and a $2,000 fine.

Just like that they transfered both to the police station and gave them both a blood test.
It came back positive for pot.
My kid was issued a ticket for ingesting pot
